2' Claims.

This invention relates to a simplified safety control device for theburner valves of gas cookmg stoves or gas ranges having their front andtop surfaces lying in right-angular planes and valves and to provide anoverhanging plate at the front portion of the cover and in right-angularrelation with the cover, for concealing the burner valves and preventanyburner valve from being open when the cover is infull closedposilOIl.

Another object of this invention is to provide a control bar attached tothe cover and being slidable relative to the under side of the cover,the cover being hinged at the rear of the gas stove to permit the coverand control bar to be swung upwardly as a unit out of the way of boththe valves and burners and to securea substantially verticalreciprocating movement of the control bar when the bar comes in contactwith a valve handle in open position.

Another object of this invention is to provide ears rojecting rearwardlyof the control bar and engageable with the valve stems, and to providemeans for engaging the slidablecontrolbar for manually moving thebarhorizontally relative to the cover after it has been swung down toclosed position and thereby complete the closing of the valves andsimultaneousl causeinterlocking engagement of the cover with the valvestems.

With the above and other objects'in view, the invention will behereinafter more particularly described, and the combination andarrangement of parts will be shown in the accompanying drawing andpointed out in the claims. which form part of this specification. A

Reference will now be had to the drawing, wherein like numerals ofreference designate correspondin parts throughout the several views, inwhich:

Figure 1 is a perspective view of a gas range having a cover in which mycontrol mechanism is incorporated, the cover being in open position.

Figure 2 is a view similar to Figure 1, but showing the cover in closedposition. V

Figure 3 is a fragmentary cross-sectional view, the section being takenas on line 3-3 in Figure 2, and showing two valve handles in open posi-131011.

Figure 4 is a fragmentary cross-sectional view, similar to Figure 3, andshows a valve handle in partl closed position. I

Figure 5 is a fragmentary cross-sectional view, the section being takenas on line 5-5 in Figure 3.

Figure 6 is a fragmentary cross-sectional view, similar to Figures 3 and4', and shows a valve handle in closed position.

In the illustrated embodiment of the invention, the numeral I0 indicatesa gas range or gas cooking stove of the cabinet type, comprising burnersII and burner control valves I2,

The gas range In is also provided with a cover I3 which is hinged on apin I4 at the rear of the gas range. The valves I2 have operatinghandles I5 by means of which the valve stems are given ninety degreemovements.

For the purposes of this invention the cover I3 is made long enoughtooverlap the valves I2. At the front portion of the cover there hasbeen provided an overhanging plate I6 which extends downwardlysufiiciently to conceal the valve handles I5.

Figure 3 is a cross-sectional view, the section being taken ason line 33in Figure 1, and shows ,a control bar or locking bar I8 in fragmentary'form. The control bar I8 is slidably mounted in concealed relation.rearward of the overhanging front plate I6. Brackets I9 fixed to thelower surface of the cover I3 provide bearings at both ends of 'thecontrol bar I8 whereby thecontroI bar I8 is attached to the cover I3.

The control bar is positioned in vertically superposed relation directlyover thevalve handles I5 when thejcoverl3 is in lowered positionover thegas range I0". The control bar has openings 20, one for each valvehandle. Onesurface portion 2| of eachopening 2:] is cam shaped andpositioned so as tocontact a valve handle when the "handleishorizontally positioned, that is, when the valve is in open position. aY

When the user swings the cover downwardly, the cam surface 2I contactsthe horizontally positioned valve handle I5 and this contacting relationremains during the continuing downward movement of the cover. At thelowest downward position of the cover, the valve handle I5 is not at itsdesired ninety degree position because of the diminished leverage at thesaid lowest position.

For the pu p se of completing the movement of th valve handle to fullninety degree valve closing position, the user applies a sidewayspressure against button 22 positioned in front of the plate I6 andhaving a stem 23 connected to the control bar 18. The stem 23 isslidably mounted in an elon a ed sl t 24 in the p ate .46, the slotbeing srtfliciently long to permit the control bar to move horizontallyand to move the valve handle l to full vertical closing position.

A latch bolt 25 is pivotally mounted one pin 26 passing through a forkedend"?! of the control bar l8. serves for engagement with an angulartopthfijl on the latch bolt 25. horizontal movement of the control bar1-8, a spring 3| secured to the plate "5 presses-the dutch .bolt 25 intoengagement with the stop 28. The

control bar is then held in fixed position horizontally and the valvehandles are then held in fully closed position.

=It-is-to be noted that ears 32, integral with \the control bar 4 8, areprovided rearward of the control bar. The ears project rearwardly of thecontrol bar a distance sufficient to "permit :the ears to clear thevalve handles and to move under the valve stems 33. In this position,the ears are bet-ween the valve handles and the casing of the gas range."The ears have upper horizontal surface which, when in engagement withthe undersuriaces of the valve stems, lock the cover I3 to the gas range[0 when the cover is in closed position and-the horizontal movement ofthe control-bar-is completed.

It will thus be noted that there has been provided aun-ita-ry cover andbuilt-in mechanism for closing the valves on gas ranges and that thisunitary device is adapted for installation as an attachment to gasranges already built.

As a safety feature against :the manipulationof the mechanism bychildren, there has :been'l'ncorporated two movements in addition to the:usual -vertical swinging movement of :the cover. It is first necessaryto use the right hand- 12p release thela'tch bolt 25 andto :usexthe lefthand to grasp :the button 22 and move the control rbar 4-8 to the leftto release the valve stems from the cover be- :iore it is po si le omovehe cov r upwar y, away from the gas range. This two hand-opera-:tional requiremen p ovides a saiety f at against the turningonef thegas by children and preventszaccidents. Y

From the above it will be seen that the gist of this invention istoproyide a uniterycover andhurnercontrol tattachmentwhichmey e attachodas a unit-on new o .onexist ng easttoves and su ported in its -.entiretyexternally r the stoves.

The demand .of ga .users is 0 ga st e ing handles, themuvements of whcha p r \totthe Imnt facecr parallel to the top face v01. the

A stop 28 is secured to the cover I 3 and pon compl tion of the V gasstove, so that their movements are solely between full vertical and fullhorizontal positions and so that mistakes can not be made in theiroperation, that is, movements wherein the handles are eitherperpendicular or parallel to one of these surfaces, as distinguishedfrom in-between angular positions.

In accordance with the patent statutes I have vdescribed and illustratedthe preferred embodi- -ments :of myinvention, but it will be understoodthat various changes and modifications can be :made therein withoutdeparting from the spirit of theinvention as defined by the appendedclaims.
